No Jerome, Please reread my post. Do not attach and motors yet. Remove them and test for voltage. That's the only way your going to see if you are getting the proper voltage you expect. You should also see a different light on the controller board light for each direction and motor. Two motors, 4 lights. Are you seeing them light?

EDIT: Ahh, is see, I was looking at Derriks pic. You need to remove the jumper blocks put a jumper between Enable A and Enable B on your board. Attach the pin closest to the edge of the board. Enable is the same as PWM. If your board is PWM capable you will be able to control the speed of your motors with it by using the PWM slider in ARC. It just changes the voltage sent to the motors (actually it's more completed then that so go a Google search).

If those are windshield wiper motors, they can pull up to 5 amps each. You are going to need a bigger controller. Also, for what it is worth, I bought two motor controllers on Ebay. One worked, the other did not. I got the defective one replaced, but eventually all three stopped working. They were rated for 68 Amps. A lot of what you get on Ebay is defective.

sorry my post is probably confusing you more. the ENa & ENb are for the PWM all you need to do is pull the plugs off, and it will expose two pins. the closer pin to the edge of the board are the ones you need to solder a wire to. I use one wire on each of them so I can have two PWM "one for each motor". you have the in1-4 plugged in correctly but I see in your picture that you do not have the +5 going into the +5 on the ez-b "the middle pin", it looks like you have it going into ext... i.e the white wire.

excuse my soldering on this

thank you at all for your answers.

derrick, I understand better with your picture.

I will keep you informed of my tests in a few days.

Hi,

Derrick, I did as you (thank you again). But I have already 1 motor works (right). I think, left connectors are out. There isn't volt on the left connectors !

Is it correct ? Left Trigger A : D8 (with D1, the motors doesn't work) Left Trigger B : D2 Right Trigger A : D3 Right Trigger B : D4

It's too late, i'll see that tomorrow.

Jerome

Jerome, sounds like you have it wired correctly.you probably have a bad hbridge, if you are not getting any voltage on the left side. Were you using a multimeter ? Left trigger a = d8 Left trigger b = d2 Right trigger a = d3 Right trigger b = d4 +5 = d5 middle +5 Ena = d6 trigger Enb = d7 trigger +12 & ground = battery + & -

Hi,

Derrick, I had the same config of you. I use a multimeter, and I've 0 volt on the left motor.

I have a question : I use the control '4 wire HBridge Movement Panel' of ARC, and I can only indicate : Left trigger a Left trigger b Right trigger a Right trigger b Consequently, Use I the good control ? Where CAN I config ENA and ENB ? Can I to try a script (is it difficult ) ?

Jerome

That's correct, the ena & enb are for the PWM control, take a look at the tutorial....
